How they qualified: Cameroon eventually powered through via the play-offs. With 13 points from six group matches, they earned a two-legged shoot-out against against Tunisia. A 0-0 draw on the road followed by a convincing 4-1 home win was more than enough to get the job done.

World Cup pedigree: Iconic. They were the first African side ever to reach the quarter-finals, losing to England in the last eight at Italia '90. Then they were guided by the inimitable Roger Milla. Disappointment has followed, though, with group exits in 1994, 1998, 2002 and 2010.

Joel Matip is one to watch.

Main man: Veteran striker Samuel Eto'o remains the main threat and still a world-class talent, though this is probably the Chelsea man's final opportunity to shine on the world's biggest stage.

One to watch: Schalke 04 defender Joel Matip, 22, is an exciting prospect. At 6ft 4in he is an imposing presence at the back for club and country. Matip bonus fact: he has a famous footballing cousin in Joseph-Desire Job.

What are their chances? Slim, especially if the rumours of squad in-fighting persist. Much will be expected of Eto'o and other senior players like Alex Song, Jean Makoun and Stephane Mbia.
